Wow, that turned out great! I especially love the head.It's a pretty interesting design, I like your partner. Glad you found a design which you are truly happy with! I always love how you give your characters songs. I think of that too, but I can never settle for one song in 95% of the cases haha.

The background is pretty good, it's neat to look at, yet it doesn't take away from the actual object. I think it turned out great despite the problems you had. The textures on Dynamon itself are a bit pale, but I don't think you wanted them to be that dominant anyways. Metal Digimon often have a few scratches and sometimes chipped parts, MAYBE that suggestion is usefull for you in any form or way.

Well my problem for a theme song is rather that the personality changes a lot on the digivolutions (if that makes any sense). But I narrowed it down so far, so I'm getting there haha

Well as pale as the textures are, there is quite a lot of it. But yeah, you only notice it when you look really close. I don't know what you intended initally, I'm guessing what you did here (lots but not directly noticable texture), but you could go with the obvious route, like 2 big scratches on the back leg and a few small ones on the neck. These are just suggestions though, it's your Digimon it looks like you want it, and I'm generally not good with machines or metal parts so take my ideas with a pinch of salt.

Hm.. interesting Digimon design.Somehow, all the Digimons' original design have something that resemblant all of them, and your Dynamon really get this!BTW, your stylish BG still amazing me! =]And I love when you put a theme music for your OC's and works! ^^
